Sure, but getting someone onto that speed dial list is part of the issue. I have a shop where I've made 3 notable purchases in the last 3 years (notable to me at least), but they're not responsive at all to any queries on availability or being able to order an item ("If we can get it, we'll put it on the website"). They also tend to default to "Is it on the list?" (and, no, a revolver made 40 years ago by a company no longer in business isn't on the list).
Sure, there are currently workarounds to much of the state's nonsense, but establishing a relationship to deal with it is part of the trick. Cold calling someone you've never met and asking if they'll do a frame transfer or the like out of the blue would seem to be inviting a response of "Call someone else, Andrea."
It could be you, not them.
